We are in full agreement that hardware that can run a 64-bit kernel should not use a 32-bit kernel. "mostly work" also applies to i386 userspace that is also slowly crumbling away, I assume noone will disagree that amd64 userspace should be the preferred option when running a 64-bit kernel (but crossgrading might be problematic). Raising awareness for these is good. > Ben. cu Adrian
